MORTISE-CATCH.

lSpecification of Letters Patent.

Patented Aug. 11, 19141.

Application led November 22, 1913. Serial No. 802,394.

To all whom it may .concern Be it known that I, JAivms M. Wnavnn, a citizen of t-he United' States, residing at Los Angeles, in the county of Los Angeles, State of California, have Iinvented new andl useful Improvements in Mortise-Catches, of which the following 'is a specification.

This invention relates to a niortise lock for small doors, drawers and the like, and the prime object of the invention is the provision of a simple form of mortise catch which will take the place of the force catches nowcommonly used and which will give all the advantages of a niortise spring bolt or spring catch lock. K

It is one of the prime objects of this inl vention to provide a lock which may be very easily and quickly mounted upon a One of the reasons why force catches have been commonly used is that they are .very easily and quickly set in a door, requiring only the boring of a cylindrical hole and setting the catch and the catch plate in place. I provide my mort-isc catch 1n cylindrical form so that it may be set in a door or the like lby a simple boring of one or more.l cylindrical holes. I greatly reduce the amount of labor necessary for setting a inortise catch; and at the same time I provide look has over a force catch. l

Although there may be many forms which my lock may take, I prefer the simple and inexpensive forni described in the following specification and shown in the accompanying drawing, in which:

Figure 1 is a horizontal section showing like, Fig. 2 is a section of the lock itself taken as indicated byline 2 2 of Fig. 1, and showing the lock in its normal position, Fig. 3 isa section similar to that of Fig. 2 showing the lock in its position with the bolt-retracted, Fig. t is a perspectivedetail the bolt tlirower, Fig. 6 is a perspective detail showing the body of the lock in section on line. 6 6 of Fig. 2 and showing the mounting of the spring l abutment plate therein.

n the drawings the numeral 10 may designate a door or the like and the numeral 11 may designate the stationary door casing. A catch plate 12 of any desired design may be mounted upon the casing; and my lock is mounted in the door 10 so that its bolt 13 may engage the catch plate.

Myvllock includes a hollow cylindrical body l5 of suitable size and length (the drawing showing the lock greatly enlarge afair and usual diameter for the body being about one-half inch) a4 cylindrical bolt 13 movable longitudinally in the body; a spring 16 holding the bolt 13 normally forwardly as shown in Figs. 1 and 2; and a rotatable thrower 18 'adapted to operate the bolt. The bolt 13 has-the ordinary pivotal face 20 on its outer end so that it may act asa latch bolt. The main part of the bolt is cylindrical, as shown in the drawings, and immediately behind' the main cylindrical portion of the bolt there are two opposite longitudinal extensions 21 which lie one above theother in the body 15 against the opposite walls thereof. These extensions are connected at their ends by transverse bar' or pin 22, upon which pin the tlirower 18 operates. A plate 23 extends across the body 15 in the space between the two extensions 21, this plate forming the abutment against which the spring 16 presses at one end, the other end of the spring being recessed into the cylindrical part of the bolt,

as at 25. The abutment plate 23 is held in the body 16 by having its ends 26 and 27 extend through openings in the walls of the body 15. This is best shown in Fig. 6. The end 27 of theplate 23 is bifurcated and the furcations extending through two openings 27a lin the body wall. The other end 26 of the plate 23 is reduced and extends through the opening 26? of the body wall. Immediately adjacent this opening 26 the body wall has a tongue 26b which may be pressed outwardly when the end 26 is inserted in the opening 26a and then be pressed inwardly again to its'- normal position .so as to hold that end of the plate 23 in place. Simple assembly is thus provided for, the bolt 13, spring 16 and plate 2,3 being assembled in the relative positions shown and then thrust into the body 15 together, the plate 23 being turned diagonally so that the end 27 will reachthe opening 27a before the end 26 reaches the opening 26, Forcing the plate `23 farther inwardly forces the end 26 under the tongue 2Gb and forces the tongue 26b out until the end 26 passes the end of the tongue and the tongue springs in behind the end 26 of the plate 23.

The rotatable thrower 18 is of the forni best shown in Fig. 5. It has a cylindrical body portion 30 with a transverse cut or slot 31, leaving a web 32 which engages the pin 22. Normally the parts are in the positions shown ,in Fig. 2; rotation or' the thrower moves the pin 22 and thereby moves the bolt 13. Excessive rotation of the thrower is prevented by a small stop pin `or lug 35 on the thrower which engages with either of shoulders 36 on the bolt extensions 21. The thrower has a squared shank 40 engageablc by a suitable knob 41. The knob is mounted upon a suitable plate 42 which may-be secured tothe outer surfaces of the door 10.

'In older to remove the thrower it is only necessary to push the boltback. into the body until the pin 22 clears the thrower. rl`he thrower may then be removed from the body leaving the body with the bolt contained therein ready to be inserted in a door in the required position. It is only 'necessary to bore two cylindrical holes to insert my catch lock, oneto contain the body and the other 'as shown at 45 in Fig. 41 to .insert the thrower. ^The body is put into the position shown in Fig. 1 and the thrower is then inserted through the bore hole 45.' The knob and plate are then placed upon the outer surface of the door. Placement of -the catch plate 12 completes the mounting of the lock.
